Change pcolor and contourf default antialiasing to False; closes 3151847.

To avoid misplaced boundaries and artifacts with alpha < 1, we do not
stroke the pcolor and contourf patch boundaries by default; but without
that stroking, antialiasing produces boundary artifacts that tend to
be visually disturbing. Therefore we sacrifice antialiasing for these
patches.
